OCI-01498
block check failure
Cause
An error occurred while checking a block with the ANALYZE command.
Action
Check the trace file for a more descriptive message about the problem and correct the errors. It may be necessary to re-create the object. The name of the trace file is operating system-specific, for example, ORA*.TRC. It is found in the directory specified by the initialization parameter USER_DUMP_DEST. If USER_DUMP_DEST is not set, trace files are not created. See also your operating system-specific Oracle Database documentation.
